The present __________ green forest of the area is a far cry from the dirty, foul smelling landfill that it was a decade ago.

Explanation: The present lush green forest of the area is a far cry from the dirty, foul smelling landfill that it was a decade ago.The options blue, complete and quite are irrelevant and do not make the sentence meaningful.

The confusion can be between the words beautiful & lush.

'Beautiful' does make the sentence meaningful but the contrast of the green forest of the area in the sentence is a dirty, foul smelling landfill that demands a more appropriate and enhancing adjective.

'lush' when used of nature, plants, trees, gardens, forests, etc. means 'rich', 'verdant' (green). Hence, lush is the appropriate word to be used for a green forest, grass, garden etc.

4) Choose one word which can meaningfully replace the underlined words in both the sentences without changing the meaning of original sentences.

1. Teachers understanding of the English subject was really good.2. The mother had to hold on to the door-handle with all her strength to get the baby out.

Explanation: Here, 'understanding' is a noun and 'hold' a verb. Of these 'grasp' as a noun means 'understanding' and as a verb means 'hold' or 'hold on to'. Hence, it can replace 'understanding' in (1) and 'hold on to' in (2). Pull, seize and compass are irrelevant and do not complete both the sentences meaningfully. Therefore, the sentences can be written as: (I) Teachers grasp of the English subject was really good.(II) The mother had to grasp the door-handle with all her strength to get the baby out.
